Answer:
Step-by-step explanation:
d₁ = 6 inches
r₁ = 3 inches
area = πr₁² = 9π in²
d₂ = 24 inches
r₂ = 12 inches
area = πr₂² = 144π in²
ratio of areas = (9π)/(144π) = 9/144 = 1/16
3 pizzas=2 side dishes
8 side dishes=8/2 times 3
=12 pizzas
The equation for a ball thrown straight up is:
y = v₀t - 0.5gt²
We don't know the initial velocity of the ball. We use the given condition from the problem that the maximum height was achieve after t = 2
y = 2v₀ - 19.62
v₀ = 0.5y + 9.81
Substituting, factoring, and replacing t with x, the result is:
